A Tragedy Forged the Vigilante. A Warzone United Him with His Dog. The must-read prequel to the Rex Dalton K9 Thriller Series.

When Rex Dalton’s family is killed in the Madrid train bombings on March 11, 2004, he emerges from the shadows with one purpose: to hunt the perpetrators who shattered lives that fateful day.

Fueled by revenge, Dalton will stop at nothing to take down the criminals targeting innocents. Known by whispered names—El Gato, Alshaytan, the Ghost—he becomes a sniper with unparalleled precision, a master of disguise, and a lethal force in close combat.

Each covert operation plunges the maverick deeper into a world marred by corruption, terrorism, and arms smuggling. But in the heart of Afghanistan, facing an opium cartel, he discovers a loyal partner in Digger, a highly skilled Dutch Shepherd military dog. As the stakes escalate and danger looms, their formidable bond becomes the ultimate weapon in Dalton’s relentless pursuit of vengeance.

The Fulcrum is the pulse-pounding first installment in JC Ryan’s electrifying K9 Thrillers series.
